Dave: I am interested in what makes you think these will improve your play in regular Go?

juhtolv: Well... Playing Atari Go and games in 9x9- and 13x13-boards is very common practise when teaching beginners. Read rest from pages of those variants. Of course, those variants have some drawbacks or at least it is sometimes considered controversial, if they are good as teaching methods. But as I said, read those pages.

Crimson : Can I put here my variants? They can get you to play better because you know that if you don't you might lose your life or some limbs.
